implication filed n@April 17, 1922.

To all whom it may concern:

Be it known that l, Earn. E. Ginn, a citizen of the United States,residing at -New York citv. boron/rh off thc Bronx in the J .f b a ilcounty oi liront: and State of New York,

have invented ce tain new and usei`ul l'rn- :provenfients in Pipe-BowlCleaners, of

which the following is a specification.

This invention relates to the class of l@ tobacco and has particularreference to irnpleinents or devices for scraping the interior snrfaceof a smoking pipe bowl.

Among the objects of the invention is to provide a small and efficientdevice of the character stated and one which may be made relativelycheap and which is adapted for convenient carrying in ones pocket, as atone end of a watch chain or the like. The device furthermore may partakeof an ornamental significance and be snitabliT plated or otherwisedecorated iii desired.

The prima object oli the invention however is to provide a pipe bowlcleaner having; two correlated legs or blades, each designed to act as aresistance member for the other leg or blade when the instrument hasimparted to it a rotating movement around the vertical axis of the bowl,one oi the blades being formed with greater curvature or conve/sity thanthe other so that it will scrape thoroughly a pipe bowl havinginanirnuno. concavity.

Jfinother object or the invention is to provide a cleaning or scrapingblade for a pipe bowl having a series or succession of chisel pointsdirected downward, whereby when the instrument is given ka reciprocatingmovement parallel to the axis of the bowl one or more oi saidchiselpoints will serve to positively and directly out or loosen anyaccumulations oi" material irons. the inner surface of the bowl, andthus with a subsequent rotation of the instrument all such accumulationswill be discharged.

With the foregoing and other objects in view the invention consists inthe arrangement and combination of parts hereinafter described andclaimed, and while the invention is not restricted to the exact detailsof construction disclosed or suggested herein, still 'for the purpose ofillustrating a prac tical embodiment thereoi3 reference is had to theaccompanying drawings, in which like reference characters designate thesaine parts in the several views, and in which- Figure l is an enlargedelevation oit e Serial Tilo. 553,52/l.

preferred forni oi the invention, a part be- .ing` in section.

2 is an edge view of the same.

Fig. 8 is a detail perspective view oithe 60 spring.

Fig. is a horizontal section on the line lf-l or Fig. l.

Fig. 5 is side elevation of a casing designed to carry the improvedcleaner as a `gether scissor fashion at 10, each leg coniprisingf a head1i, a shank 12, and a blade, one leg having a blade 13 and the other a.blade 14.

Each head is wider than the adjacent connected shank portion The springlo l prefer to employ is bow shaped has its ends slitted, forming aseries or three ngers 17 and i8. The fingers 17 lie against the innersides of the heads il, while th pairs are turned at an angle to thelinger l? and embrace the Shanks 12 directly against the shoulders l5.Covering each head ll is a cap 19 constituting a iinger piece and afinish for the handle. Each well over finger portions of the adjacentend or the spring and is crimped down around such parte as shown at 20,'producing an effective interloc holding the spring in the placeindicated and the cap from .losing oil" orla the head.

The blade i3 is shown provided with a series ot teeth 2l, preferablychisel shaped and directed downward so that with the recinrocation ofthe instrument un and down,

parallel to the oi the bowl into which either or both of the blades ci'the cleaner may be Jnrojected at least one of the chisel points of theteeth will cut the material on the pipe bowl from the surface thereof,m0

thoroughly cleansing the same. lf the bowl is formed with maximumconcavity the lower-most chisel points at least will engage everyportion thereof while the instrument is moved :trom one end of the bowlto the 305 other and also given a slow rotatingr movement around theaxis of 'the bowl while the cutting action due to the recinrocations ofthe instrument is continued. This action ci the chisel points or teethmay be resorted to M6 somewhat infrequently for the reason that theusual cleaning or scraping action may forming shoulders l5. 75

fingere i8 formed in 80 cap entends S5 be performed by the square sharpedge portions 22 of the blade 14. These edges will always engage sharplywith the surface of the bowl du bo the curvature as suggested by thedotted arc 23, Fig. fr. The chisel points may be slightly rounded asshown in this 'irure to increase the scraping action whilebeingreciprocated.

The ends o r points or" the blades may have any suitable shape toproject into and scrape the pit of the bowl, and they are preferablyprovided with relatively sharp knife edges 24. These ends ci the bladeswill strike against each other to limit the swing of the blades towardeach other and thereby the spring, whose function is to separate theblades, will not be over strained.

In practice for ordinaryl cleansing or scraping of the bowl theinstrument is plunged directly into the bowl with the handles extendedabove the bowl in position to be rotated or twisted around the axis ofthe bowl. The depth to which the instrument is projected into the bowlwill depend upon the depth ci the bowl and its interior shape, but inmost instances the blades will. accommodate themselves directly tovarious sizes and shapes of bowls, the spring acting at all times tocause both blades to engage against opposite sides of the bowl, whereb)Yeac-h blade is a resistance for the other. the accumulations arepersistentl they may be dislodged by imparting a reciprocating movementto the instrument as already set forth.

The device is designed in a neat and convenient form so as to be carriedin a relatively srnall shell or casing 25 and suspended from a watchchain by a ring 26, or other.- wise carried in ones pocket as a pocketpiece.

l claim:

l. ln a pipe bowl cleaner, an abrading member arranged for action withits axis approximately parallel to the axis of the bowl and having arounded cutting chisel edge lying in a plane transverse to said axis.

2. ln a pipe bowl cleaner, the combination of a pair oi' oppositclyarranged scraping blades movable toward and from each other, and aspring acting upon the blades to cause them to separate and thereby hugthe opposite sides of the bowl, said spring having slitted ends, andmeans embracing said ends to hold the springin position.

3. ln a pipe bowl cleaner, the combination ot two relatively movablescraping members pivoted together and having linger pieces at theirouter ends, said nger pieces comprising caps slipped over the ends ofthe members, and a leaf springw located between the ni mbers and having'its ends slitted to emla the members while said ends are enibraced bythe linger pieces and thereby held in position.

il. A device as set forth in claim 3 in which the ends ot' the scrapingmembers are provided with shoulders and the ends of the spring areslitted to 'form fingers embracing the ends and abutting against saidshoulders, and the finger pieces extended over Vthe slitted ends of thespring to hold the same against said shoulders and prevent the fingerpieces from accidental removal.

ln testimony whereof l aliix my signature.
